Completely agree.

Definitely need to make quite a few defvar's there into defcustom's,
including separate binary/args.

s/dash deps (pretty sure I use cl-return and let* too) are only
omitted because it's in the repo where I use them all over the place,
and would be better to drop them entirely for emms code to avoid new
requires there.

Will be sure to address all these, thanks a lot for pointing them out!
